Efate Ground Dove (Pampusana sp.)

This form is known on the basis of subfossil remains that indicate a bird of similar size to the Friendly Ground Dove (Pampusana stairi (Gray)), a species that inhabits the islnds of western Polynesia.

The Efate Ground Dove was sympatric with the still existing smaller Santa Cruz Ground Dove (Pampusana sanctaecrucis (Mayr)). [1]
